Complete guide to enterprise WeChat interface docking: PHP developers must learn

With the rapid development of enterprises, the need for internal communication and collaboration is becoming more and more urgent. As the leading enterprise-level communication tool in China, Enterprise WeChat provides enterprises with one-stop office solutions. For PHP developers, learning how to interface with Enterprise WeChat will become an important part of improving work efficiency. This article will introduce in detail the entire process of enterprise WeChat interface docking and provide PHP code examples.

1. Obtain access_token

Before connecting with Enterprise WeChat, you first need to obtain access_token as a credential for subsequent interface calls. The following is a sample code to obtain access_token:

<?php
$appid = "YOUR_CORP_ID";
$secret = "YOUR_CORP_SECRET";

$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$appid&corpsecret=$secret";

$result = file_get_contents($url);
$data = json_decode($result);

$access_token = $data->access_token;
?>

In the code, replace YOUR_CORP_ID and YOUR_CORP_SECRET with your own corporate WeChat CorpID and CorpSecret.

2. Sending Messages

One of the main functions of Enterprise WeChat is the sending and receiving of real-time messages. The following is a sample code for sending text messages through the enterprise WeChat interface:

<?php
$access_token = "YOUR_ACCESS_TOKEN";

$url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=$access_token";

$data = array(
    "touser" => "USER_ID",
    "msgtype" => "text",
    "agentid" => 1000001,
    "text" => array(
        "content" => "Hello, World!"
    ),
    "safe" => 0
);

$options = array(
    "http" => array(
        "header" => "Content-Type: application/json",
        "method" => "POST",
        "content" => json_encode($data)
    )
);

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
?>

In the code, replace YOUR_ACCESS_TOKEN with the access_token obtained previously, and replace USER_ID with the user ID to which the message is to be sent. The contents of msgtype, agentid and text can be adjusted as needed.

3. Receive messages

In addition to sending messages, Enterprise WeChat can also receive messages from users and process them accordingly as needed. The following is a sample code for receiving text messages:

<?php
$token = "YOUR_TOKEN";
$encoding_aes_key = "YOUR_ENCODING_AES_KEY";
$corp_id = "YOUR_CORP_ID";

$xml = file_get_contents("php://input");
$xml = urldecode($xml);

$cryptor = new CorpWXBizMsgCrypt($token, $encoding_aes_key, $corp_id);

$decrypted = '';
$errCode = $cryptor->DecryptMsg($_GET['msg_signature'], $_GET['timestamp'], $_GET['nonce'], $xml, $decrypted);

if ($errCode == 0) {
    //解密成功，处理业务逻辑
    $data = simplexml_load_string($decrypted);
    $content = $data->Content;
    $userId = $data->FromUserName;
    //根据用户发送的消息做出相应的回复
    //...
} else {
    //解密失败，记录错误日志
    //...
}
?>

In the code, replace YOUR_TOKEN, YOUR_ENCODING_AES_KEY and YOUR_CORP_ID with your own enterprise WeChat Token, EncodingAESKey and CorpID.
